Prevalence of Extracranial Carotid Artery Lesions at Duplex in Primary Aldosteronism

Renovascular hypertension and high renin hypertension were found to be associated with an excess prevalence of carotid artery atherosclerotic lesions and to a higher risk of stroke, respectively, as compared to low-to-normal renin hypertension. Primary aldosteronism, being characterized by hypertension and a chronically suppressed plasma renin activity, should be accompanied by a low prevalence of carotid artery lesions. To verify this hypothesis we investigated prospectively, by a high resolution duplex ultrasound technique, the prevalence of extracranial carotid artery lesions in a case-controlled study of 34 (22 women and 12 men, aged 22 to 76 years) patients with no history or symptoms was diagnosed in 17 patients
